CIRCULATION SYSTEM FOR AUTOMOBILES.

State of Ohio, have invented certain new and useful Improvements in Circulation Systems for Automobiles, of which the following is-a specification, reference being had therein to the accompanying drawing.

"This invention relates to automobiles and the water circulation P system employed to cool the engine of an :atQI'S; and also 'latlng the coollng act1on of the radiator on the water.

automobile.

The object of the invention is twofold; first, to provide means to prevent the cooling fluid from freezing in the engine or radiator; and second, to provide means for passenger compartments of the warming the automobile.

To this end it is also an object of the invention to provide means to drain the fluid from the water jackets, radiator and connecting p'pesinto a receptacle which is so the fluid in the same will not freeze; and further, to connect the system devices, such as heatarranged in the pas- Speciflcation of Letters Patent.

Suitable means are provided for maintaining the cirthe water jacket.

in front'of the engine and connected to the I stand idle for any length of time during cold weather. To accomplish this I prefer to utilize a suitable water receptacle, such as a tank 6, which is supported adjacent to the circulation system and is here, shown as supported beneath the frame of the automobile. This tank is completely ,surrounded with insulating material, such as wool fiber and asbestos, as indicated at 7, and is so protegted that its contents will not freeze even in the most severe weather. Mounted within the tank and connected with the circulation system is the usual pump 8 by means of which the water is forced through the conduits, water jacket and radiator. Preferprovided with a depressed portlon forming a well within which the pumpvis mounted. By this means a sufficient depth of water is provided to enable the pump to operate until the tank is practically empty. In the form of the tank here shown the well is formed by a section 9 separate from and detachably secured to the main tank 6 by means of bolts 10. i This well section is protected in the same manner as is the tank proper and in fact forms a part of that tank therewith.

In the normal operation of the system the water which is discharged from the water jackets through the pipes 3 and 5 into the radiator 4 returns to the tank through a pipe 11 which is connected by means of a valve 12 with a short discharge into the tank. The valve 12, which is preferably a four-way valve, is also connected with a pipe 14: leading rearwardly along the passenger compartments such as foot partments. Each heater comprises merely a shallow casing, one wall of which forms a foot plate. Thiscasi'ng is provlded w1th an which leads to the tank and is smaller than the inlet. Consequently, the

, easing will be kept full of water and the foot may not freeze in the water jacket or in the radiator 4, which is here shown as arranged .plate will be heated.

culat on of water through the conduits and h eaters maybe provided and they may be arranged in any desired positions. The outy number of these and is in open communication pipe 13 arranged to passenger COlIl- V nected at that end thereof opposite the pipe- 5 which connects the outlet pipe to the radiator. Valves 18 and 19 are interposed between the pipes 5 and 17, respectively, and

the outlet pipe 3 and are so connected that when one of these valves is in its open position the other willbe closed. This connec-' tion is preferably formed by a rod 20 which valve. Any suitable means may be provided for indicating on the dash the position of.

the valve. It will be apparent that with the valve 18 open and the valve 19 closed the water which passes through the outlet pipe 3 will pass through the radiator, thence throughLthe with the pipe 11. Consequently,.the Water pipe 11 and valve 12. If this valve is set to connect the pipe 11 with the short pipe 13 the water will be discharged into the tank and then again pumped through the system to maintain theusual circulation. If the valve 12 is set to connect the pipe 11 with the pipe 14: then the water from the jacket will pass through the heaters before it reaches the receptacle. If the circulation of the water through the heaters to the tank will cool the same sufficiently it may be de-' sirable to cut out the radiator and deliver the water directly to the heaters from the water jackets. This can be done by opening the valve 19, closing the valve 18 and setting the valve 12 to connect the pipe 17 with the pipe 14:. If it is found that the heaters arenot-sufficiently heated with the water passing through'the radiators and" heated too much if the radiator is cut out altogether the temperature may be regulated 'by providing means, such as a curtain 25, to out 01f partly or entirely the passage of the air through thegradiator and thus regulate the extent to which the water will be cooled while in the radiator. At the end of a run when the engine is to stand idle for any material length of time in cold weather the. valve 12 is set to connect the pipe 13 in the radiator and pipe 11 will drain into the tank and the water in the jackets and outlet pipe 3 will drain through the pump into the tank, Thetank being effectually insulated there will be no freezing of the water in the tank and there will be no water in the water jacket or any part of the circulating system to' freeze. 1

While I have shownand described one embodiment of the invention it will be understood that the same has been chosen for the purpose of illustration only and that I 1. An anti-freezing circulation system comprising an engine having a water jacket,

a radiator, a conduit connecting said water jacket with said radiator, and a water receptacle supported adjacent to said engine and said radiator, conduits connecting said receptacle with said water jacket and said radiator, and a pump mounted in'said receptacle to force water from said receptacle through said water jacket and said radiator, the several parts of said circulation system being so arranged relatively one to the other and to said receptaclethat the water in said system will automatically drain into said receptacle when the operation of said pump is interrupted. y

2. The combination, with an engine having a water jacket,'of a cold-resisting water receptacle mounted below the level of said water jacket, conduits connecting said receptacle with said water jacket and arranged to drain into said receptacle, and a pump mounted in said receptacle to force the water from said receptacle through said conduits and into. said water jacket.
